Multiple Choice

Which hormones are able to enter the cell to bind to the receptor?

• Lipid Soluble
• Water Soluble
• Protein Soluble
• Carbohydrate Soluble

Multiple Choice

What chemical is generally the "second messenger"?

• cAMP
• Ach
• Water Soluble Hormones
• Steroid Hormones

Multiple Choice

Which type of hormone causes an activation of genes?

• Water Soluble
• Lipid Soluble
• cAMP
• Ach

Multiple Choice

How do hormones travel to target cells?

• Blood Stream
• Ducts
• Secretory Vessicles
• Goblet Cells

Multiple Choice

Which hormones utilize cAMP in order to cause an effect in a Cell?

• Steroids
• Lipid Soluble
• Water Soluble
• Androgens

Multiple Choice

Hormones that direct and control the activities of other hormones.

• somatomedins
• beta blockers
• growth hormones
• tropic hormones

Multiple Choice

Which cells respond to hormones?

• Target Cells
• Endocrine Cells
• Exocrine Cells
• Muscles and Nerves

Multiple Choice

Which class of hormones will stop the activity of a target cell?

• Inhibiting
• Stimulating
• Releasing
• Secreting

Multiple Choice

Produces oxytocin

• anterior pituitary
• posterior pituitary
• hypothalamus
• pancreas

Multiple Choice

Cuddle hormone. Released by the posterior pituitary.  

• prolactin
• oxytocin
• aldosterone
• melatonin

Multiple Choice

The gland located near the brain; below the hypothalamus at location A is:

• Pituitary

• Thyroid

• Adrenal

• Testes

Multiple Choice

What hormone is responsible for the production of milk in the breast?

• prolactin
• oxytocin
• estrogen
• follicle stimulating hormone

Multiple Choice

What is the target for antidiuretic hormone?

• liver
• thyroid
• kidney
• pancreas

Multiple Choice

The role of adenylate cyclase in hormone activity is to

• convert ATP to ADP

• convert ATP to cAMP

• catalyze the release of the hormone from its receptor site

• act as a receptor to water soluble hormones

Multiple Choice

If we compare hormones to keys, then locks are:

• Receptor sites in the target tissues.

• Releasing hormones or factors in the hypothalamus.

• Regulating hormones released by the anterior pituitary gland.

• Hormones bound to plasma protein in the blood.

• None of the above

Multiple Choice

When levels go above or below a set point a hormone is released to return the body to set point. When the body is restored to set point no more hormone is released. This is an example of...

• a positive feedback loop
• a negative feedback loop
• a neutral feedback loop

Multiple Select

Which of the following are caused by hormones

• increase enzyme production

• activation of enzymes

• increase cell protein production

• initiate DNA trascription

• initiate DNA synthesis

Multiple Choice

All water soluble hormones use cAMP as a second messenger.

• True

• False, all lipid soluble

Multiple Choice

Which hormone affects reproductive organs?

• ACTH

• follicle stimulating hormone

• cortisol

• thyroid stimulating hormone

Multiple Choice

Which hormone can cause skin tone to darken?

• Human chorionic gonadotropin

• ADH

• Melanocyte-stimulating hormone

• parathormone

Multiple Choice

Which gland in the diagram secretes melatonin?

• a

• b

• c

• d

• e

Multiple Choice

Which does letter C represent in the diagram?

• anterior pituitary

• posterior pituitary

• hypothalamus

• infundibulum

• none of the above

Multiple Choice

How do lipid-soluble hormones differ from water-soluble hormones?

• Lipid-Soluble Hormones can go through the cell membrane and water-soluble hormones cannot.

• Lipid-Soluble Hormones cannot go through the cell membrane and water-soluble hormones can.

• Lipid-Soluble Hormones target cells inside ducts and water-soluble hormones target cells deep outside ducts.

• Lipid-Soluble Hormones target cells deep inside the body and water-soluble hormones target cells superficially.

Multiple Choice

Can pass through the membrane because of their chemical similarity to fatty acid chains in cell membrane.

• Water-Soluble Hormones

• Lipid-Soluble Hormones

Multiple Choice

Which hormones are able to enter the cell to bind to the receptor?

• Lipid Soluble

• Water Soluble

• Protein Soluble

• Carbohydrate Soluble
